Whistleblowers, oracles and prophets

Conspiracy theorist's wet dream. A massive nationwide cyberattack kills thousands. A former president George Mullen (Robert De Niro) is appointed as the head of Zero Day Commission to investigate the attack, find and imprison the fuckers who did it. The series started out well, the slow-burning pacing was exciting, and the performances were brilliant, but the final moments (the last two episodes) watered it down.
